Disclosed are techniques, devices and systems that provide a compact reservoir and plunger arrangement. In the disclosed examples, a reservoir may include a housing, a plunger, a lead screw and an elastic sleeve. The housing may have a first end and a second end. The plunger may be configured to fit within the housing. The leadscrew may be coupled to the plunger. The elastic sleeve may surround the leadscrew and be coupled to a surface of the plunger and to a surface of the second end of the housing. The elastic sleeve is leakproof.

A plunger configured as described herein provides geometry optimizations to minimize friction magnitude and variability during use by maintaining low deformation under large extrusion forces. More specifically, plunger embodiments described herein minimize a contact area between the plunger and a syringe or chamber, while also maintaining high contract pressures to maintain container closure integrity. Moreover, the plunger embodiments are configured to have minimal or no increase in the contact area under high loads associated with the delivery of viscous products.

There is provided drug delivery devices comprising a drug container assembly with a needle and automatic needle insertion and drug delivery mechanisms. Aspects of the devices described include a noise-generation mechanism to indicate the completion of drug delivery, a mechanism for triggering drug delivery following needle insertion, front-end activation of the device and a safety mechanism for covering the needle after use and methods of assembly of the devices.

Systems, devices and method to establish fluid communication between vessels. A vessel having at least two entry ports and at least one exit port, and at least one container containing a dosing regimen, the at least one container configured to be received by one of the at least two entry ports of the vessel, whereby upon connection of the at least one container to the one of the at least two entry ports of the vessel, the dosing regimen in the at least one container is transferred into the vessel. Modular dosing system for adding at least one amount of a medicament to a preparation in a modular construction. System for displaying a dosing regimen or single amount of a medicament, so that the administrator of the amount is able to precisely ascertain the amount administered to a patient.
